If your machine did not come with a Mac OS 9 System CD, skip to step 2.

1. Put in the Mac OS 9 System CD that came with your machine, and select it as the startup disk. Then perform a Clean Install of Mac OS 9. That should get you back a bootable Mac OS 9 System Folder. Skip to step 3.

Previous System Folder -> Preferences to System Folder -> Preferencesmaking sure not to replace any files, except when they are your Explorer, Netscape or other browser preferences you might have had in Mac OS 9. Quicktime Preferences can be replaced by the old ones if you had Quicktime Pro. Remote Access preferences should also be replaced if you don't recall your password on a dialup internet account. Migrate over from Previous System Folder to System Folder any other missing folder that doesn't get replaced when you do the move.

Then you should be able to boot Mac OS 9 without a problem.

Use Extensions Manager to weed out any older versions of Extensions or Control Panels when you boot into Mac OS 9 by holding down the spacebar on restart, restarting into Mac OS 9 using the Startup Disk System Preference under Mac OS X. Do not attempt to enable any old extensions until you verify you need them under the Classic environment, and preferably, you should upgrade all your peripheral support to:

Mac OS X native versions as the base extension set + the Classic extensions is the most stable under Classic you can ask for. Use other extensions only when booting into Mac OS 9, and Repair Permissions when done using Mac OS 9 applications under Classic or booting into Mac OS 9.
